Search system properties

Sets the number of Search queries that can execute in parallel. Consider increasing this value or reducing client/driver requests per connection if EnqueuedRequestCount does not stabilize near zero.
Default: The default is two times the number of CPUs (including hyperthreading).
timeAllowedoption is enforced by default to prevent long-running shard queries (such as complex facets and Boolean queries) from using system resources after they have timed out from the DSE Search coordinator.
DSE Search checks the timeout per segment instead of during document or terms iteration.
The system property
By default for all queries, the
timeAllowed value is the same as the

Using the Solr
Set the <path> to store DSE Search data. See Set the location of search indexes.
Set a custom number of fuzzy query expansions. Solr is hardcoded for 50 max expansions. This property allows you to override, up to a maximum value of

To disable, set to false to pass the offheap JVM system property at startup time. When not set, the default is true.
